The utility model can prevent the items in the bag from being oxidized by oxygen, and can also prevent some relatively fragile items from being crushed due to vacuuming.

[0004] However, the device still has some shortcomings: when in use, the device cannot clamp and fix the objects that need to be filled with nitrogen, so during processing, the objects may be offset and the effect of nitrogen filling may be reduced, which reduces the working efficiency of the device to a certain extent.
